Blue COB LED Strip — 3.28 FT

This 3.28-foot COB LED strip emits a uniform blue light at 320 LEDs per metre. It runs on DC 5 V USB power and mounts on an 8 mm wide double-layer copper PCB with 3M adhesive backing. The 180-degree beam angle provides broad, even illumination for indoor projects.

USB Controller and 3M Tape

A three-key USB dimmer adds six brightness levels and on/off control without extra wiring. The 3.28-foot power cable reaches common USB ports on chargers, hubs, TVs or computers. Strong 3M tape bonds to clean, dry, smooth surfaces for quick installation.

Indoor Accent Lighting Only

Suits hobbyists adding bias lighting behind monitors, under-cabinet glow or 3D-printer illumination where a single blue hue is wanted. IP30 rating and 5 V operation rule out outdoor, wet or high-voltage installations; buyers needing colour change, waterproofing or longer runs should look elsewhere.

Questions about this item

How long before the 320 LEDs per metre COB strip needs replacing?

The manufacturer rates the double-layer copper PCB strip at more than 65,000 hours of operation.

What limits continuous running of the 5 V USB-powered strip?

The 7 W per metre draw and IP30 rating mean heat builds up in the 8 mm copper board during all-day use.

How much heat and noise does the 3.28 ft blue strip produce when left on?

It runs silently at low 5 V voltage; warmth stays modest thanks to the double-layer copper PCB.
